What is a magnet simple definition?

A magnet is a piece of metal with a strong attraction to another metal object. The attraction a magnet produces is called a “magnetic field.” Most magnets are made of iron or an iron alloy, and magnets are at the heart of many common items like cassette tapes, credit cards, toys, and compasses.
